Thanks for the information. It helps me to understand a bit. I must admit that this is knowledge that I have little mastery of.
But why by extracting the texture (jpeg) and re-creating it works? The "extra data that SketchUp has with that in an xml file" changes?
That said, I believe this is a problem that has happened to me a few times. Identifying where the error comes from is not obvious. I don't know yet how to understand error information like "Vulkan Error: vk::Queue: ErrorDeviceLost at queue submit" What it actually tells me. From what I understand is that there is a buggy information transfer? This is not a particular problem with SketchUp or Enscape as such. But this error can occur with other software (?)
From now on, I will test more often the textures that come from the warehouse. It's pretty much the only way I can think of to avoid endless searching.
A big thanks!
